.444 reloading - issue with lever on rifle.

Hello - not sure if this is something to be concerned with or not, but I'll pose the question regardless.

I have close to a dozen different projectiles for my .444 Marlin, its a gun I really enjoy shooting so I want to find a load that is the perfect mix of accuracy, economics, and fun. This weekend I loaded up a batch of 300gn hard cast round-nose rojectiles (with the very tip flattened) and experienced an issure i've not had before - when I feed a round in and lever it into the chamber, the last 1/4" or so of closing the lever takes some extra muscle to accomplish. It does not close in a single-movement fashion, it gets to that last point and then needs to be squeezed harder to snap closed.

The gun is a 1969 Marlin medallion, and it has not done this with other projectiles I've loaded. Most notably, I also have some 300gn copper projectiles that are round nosed (fully rounded) and are almost identical to the 300gn casts I tried this weekend, but I did not have this lever-closing issue with them.

The casts in question do have a cannelure, but I did not seat to it - I seated probably less than 1mm under the cannelure in order to get an OAL that the gun really liked with the 300gn copper projectiles. I put a light crimp on them where they sat. I did fill the tube mag with them and fed a mag through the gun, and it cycled just fine, aside from the hard to close lever. When I fired them, I only loaded one at a time, as this is a new load and that's just my process until I work out a load I can trust, then I'll fill the mag when I shoot.

I thought maybe even though the OAL is what the gun liked, that with this projectile maybe I needed to seat a little lower; maybe I was pushing the round into the rifling when chambering, but I have my doubts: again, the OAL matches that of another almost identical round I have had, and after feeding a round and then ejecting it a few times, I can see no evidence on the cast round that it has been touching anything: they are hard cast, but still easy to mark, and I don't see when it might have been pressed into anything. I have not had time to try and seat one a little further to the cannelure to see if that will fix the problem, but it would be confusing if it did - like I said, I've got 1mm or less to get to the cannelure, and the lever needs an extra squirt of mustard to close at around the 1/4" mark - thats a big delta between the 2, and seating the bullet an extra 1/4" makes no sense - nothing would be left exposed.

I did fire the rounds, and they shot fine. I have targets set up at (approx) 40, 70, 100, and 150 yards, and I hit them all with decent grouping. I fully inspected the brass and gun after firing, no signs of any trouble - I used brand new never shot brass, once fired it was fine (no stretches, scratches or marks, or crushed mouths), my barrel looked great and no leading or other signs of concern.

Closing the lever does not take a jarring action, 2 hands, or any silly amount of force. I just have to squeeze it harder to get it done. I'm only asking because I have not had this happen with opther projectiles, so I'm a little stumped and just wondering if there are some out there with more experience that can suggest something else to look for or try.
 
possible you are pushing them into the rifling. Id seat deeper until they cycled smooth. I used the short hornady brass for big cast bullets in mine.
 
If you're are not pushing them into the rifling (which was my first thought) and it doesn't sound like you are if they are not marked, your bullets are maybe oversize. Cast bullets are often oversized a bit for a better fit in the barrel. Jacketed bullets for the .444 are .429 but cast bullets for the .444 are often sized to .432. That often creates a slight bulge when you seat your bullet which could be the cause of the slight resistance you're feeling. I also shoot a .444 Marlin.
 
I don't have my data in front of me at the shop, but I know I don't have any cast rounds that are .432. The 300gn copper rounds are .430, and I believe these 300gn casts are as well - they are .431 max. They actually seated very nicely when reloading - I was using new brass for them, and I did a super light neck flare/size, and after loading 50 rounds I had shaved zero lead and just had some really minimal scraps of wax lube left over when I was done.

When I close the shop I will seat one a little further and see if that makes any difference, but if it does I might be more confused.

Like I said, they shot pretty good, but I don't want to cause any trouble for the rifle, and certainly not me.
 
No. You;re referring to blackening the bullet to see what marks are made in it when chamering?

I didnlt get around to fussing with it last night, but I'll do that as well I guess.

...sometimes this simple action can show up some hidden consistencies...you can even candle onto the neck (or for a .444 use your imagination! ;)) of your case...it's free...always loved .444...you're a lucky man to have one!
 
Well, I seated a round literally less than 1mm deeper, and it chambered just find with no extra lever squeeze required. I find it really confusing, because the oal is now shorter than a different round with a nearly identical shape and weight, and taking so little away from the length removed about a 1/4" or so that the lever was stopping at. But, I'm no gunsmith, I just shoot the damn things.

I won't lose any sleep over it I guess, but I do wonder how it will affect my goups - positively or negatively.

Thanks to all for your suggestions,
 
...the ogive describes the curvature of the bullet itself as it comes to the end. some bullets have a fuller ogive and therefore touch the lands before bullets with more gradual ogives. i had to deepen the throat on my .45-70 in order to accommodate the 500 grain bullets i cast
